FIELD OF THE DISCLOSURE

The present disclosure is generally related to providing audio content.

BACKGROUND

Many people enjoy multimedia content. Television and films provide sources of information and entertainment that envelop the senses more than other forms of recreation, such as reading. Additionally, some multimedia outlets provide multiple unrelated types of information, in conjunction with news or entertainment programs. As a result, display space within a user's primary field of vision, such as during a television program, is valuable and often crowded, as information and content providers compete for the user's attention.

One consequence of multimedia entertainment is the distraction that it causes. The brightness of many displays and the availability of desired content on demand can divert a user's attention from other tasks, such as reading or supervising children, even during an informational program. In many cases, users may wish to listen to audio content, including recorded music, live radio broadcasts, or the audio portion of a television program or recorded movie. However, gaining access to so many forms of audio content requires the user to purchase and operate separate entertainment devices, such as a television, stereo receiver, set-top box, and DVD player. The proximity and time required to manipulate these different devices can also detract from other activities, even where each device may be operated by a remote control. Accordingly, there is a need for an improved system and method of providing audio content.

In an exemplary, non-limiting embodiment, each set-top box device 116, 124 can receive audio, data, video, or a combination thereof, from the client-facing tier 102 via the private access network 166. The set-top box 116, 124 can output the audio, display the data, or transmit the video to an external display device, such as a television monitor 118, 126. Further, the set-top box devices 116, 124 can include a STB processor, such as STB processor 182 and a STB memory device, such as STB memory 184 that is accessible to the STB processor 182. In a particular embodiment, the set-top box devices 116, 124 can also communicate commands received from the remote control devices 120, 128 back to the client-facing tier 102 via the private access network 166.

In an illustrative embodiment, the client-facing tier 102 can include a client-facing tier (CFT) switch 130 that manages communication between the client-facing tier 102 and the private access network 166 and between the client-facing tier 102 and the private network 110. As shown, the CFT switch 130 is coupled to one or more data servers 132 that store data transmitted in response to user requests, such as video-on-demand material. The CFT switch 130 can also be coupled to a terminal server 134 that provides terminal devices, such as a recorded audio server 172 and other devices, with a common connection point to the private network 110. In a particular embodiment, the CFT switch 130 can also be coupled to a video-on-demand (VOD) server 136.

As illustrated in FIG. 1, the application tier 104 can communicate with both the private network 110 and the public network 112. The application tier 104 can include a first application tier (APP) switch 138 and a second APP switch 140. In a particular embodiment, the first APP switch 138 can be coupled to the second APP switch 140. The first APP switch 138 can be coupled to an application server 142 and to an OSS/BSS gateway 144. The application server 142 provides applications to the set-top box devices 116, 124 via the private access network 166, so the set-top box devices 116, 124 can provide functions, such as display, messaging, processing of IPTV data and VOD material, etc. In a particular embodiment, the OSS/BSS gateway 144 includes operation systems and support (OSS) data, as well as billing systems and support (BSS) data.

Further, the second APP switch 140 can be coupled to a domain controller 146 that provides web access, for example, to users via the public network 112. The second APP switch 140 can be coupled to a subscriber and system store 148 that includes account information, such as account information that is associated with users who access the system 100 via the private network 110 or the public network 112. In a particular embodiment, the application tier 104 can also include a client gateway 150 that communicates data directly to the client-facing tier 102. In this embodiment, the client gateway 150 can be coupled directly to the CFT switch 130. The client gateway 150 can provide user access to the private network 110 and the tiers coupled thereto.

In a particular embodiment, the set-top box devices 116, 124 can access the IPTV system 100 via the private access network 166, using information received from the client gateway 150. In this embodiment, the private access network 166 provides security for the private network 110. User devices can access the client gateway 150 via the private access network 166, and the client gateway 150 can allow such devices to access the private network 110 once the devices are authenticated or verified. Similarly, the client gateway 150 can prevent unauthorized devices, such as hacker computers or stolen set-top box devices from accessing the private network 110, by denying access to these devices beyond the private access network 166.

For example, when a set-top box device 116 accesses the system 100 via the private access network 166, the client gateway 150 can verify subscriber information by communicating with the subscriber and system store 148 via the private network 110, the first APP switch 138 and the second APP switch 140. Further, the client gateway 150 can verify billing information and status by communicating with the OSS/BSS gateway 144 via the private network 110 and the first APP switch 138. The OSS/BSS gateway 144 can transmit a query across the first APP switch 138, to the second APP switch 140, and the second APP switch 140 can communicate the query across the public network 112 to the OSS/BSS server 164. After the client gateway 150 confirms subscriber and/or billing information, the client gateway 150 can allow the set-top box device 116 access to IPTV content and VOD content. If the client gateway 150 cannot verify subscriber information for the set-top box device 116, e.g., because it is connected to an unauthorized twisted pair, the client gateway 150 can block transmissions to and from the set-top box device 116 beyond the private access network 166.

In another embodiment, the multi-channel amplifier can communicate with more than two speakers 332, such as a surround sound audio system.

In a particular embodiment, one or more voice commands 334 are received at the audio input device 326. The voice command(s) 334 are transmitted to the voice command logic module 310. The voice command logic module 310 can be hardware logic adapted to receive voice commands 334 from the audio input device 326 and transmit corresponding signals or commands to the media control logic module 304. Alternatively, the voice command logic module 310 can include a device that contains computer-readable instructions to process the voice commands 334 and transmit corresponding signals to the media control logic module 304. In another example, the voice command logic module 310 can be a combination of hardware and computer-readable instructions suited to receive voice commands 334 from the audio input device 326 and transmit corresponding signals or commands to the media control logic module 304. In one embodiment, the voice command logic module 310 can be a voice card.

The commands or signals that are transmitted by the voice command logic module 310 can be received and processed by the media control logic module 304. In a particular embodiment, the media control logic module 304 can include hardware logic adapted to carry out a variety of functions, based at least partially on the voice command(s) 334. Alternatively, the media control logic module 304 can include a device that contains computer-readable instructions to perform functions, based at least partially on the voice command(s) 334. In another embodiment, the media control logic module 304 can include a combination of hardware and computer-readable instructions suited to perform functions, based at least partially on the voice command(s) 334.

For example, the media control logic module 304 can retrieve audio content and related data identified by the voice command(s) 334 received at the audio input device 326. In one embodiment, the media control logic module 304 can submit one or more queries to the memory device 306 and retrieve audio content and related data that match or at least substantially match the voice command(s) 334 from the audio content and information files 320. In another embodiment, the media control logic module 304 can submit one or more requests for the audio content to an IPTV system, via the private IPTV access network 322. In this embodiment, the media control logic module 304 generates one or more requests and transmits the one or more requests to the private IPTV access network 322, via the network interface 308.

In an illustrative embodiment, the media control logic module 304 can include instructions to output audio content and related data that it receives from internally stored audio content and information files 320, the external private IPTV access network 322, or both, to the speakers 332. The media control logic module 304 can generate and transmit an audio signal 336 corresponding to the audio content to the audio amplifier 316. Further, the audio amplifier 316 can amplify the audio signal and transmit the amplified signal to the speakers 332, via the audio output interface 330.

Audio content can include radio content, such as broadcast radio, Internet radio, or satellite radio content; recorded audio content, such as MPEG audio layer 3 (MP3) or Wave files; audio content of a broadcast television program, such as a live or syndicated broadcast program; audio content of a recorded television program, such as a television program recorded via a digital video recorder 340 or a program stored at a server that is accessible via the private IPTV access network 322; audio content of a recorded video program, such as video-on-demand (VOD) content or a movie recorded or stored at the DVR 340; or a combination thereof.

Additionally, the media control logic module 304 can transmit data 338 related to the audio content to the display 314. The data 338 related to the audio content can include a song title, a song collection title, an artist name, a song track number, a user-defined audio file identifier, a radio station frequency, a radio station call letter, a radio station call number, a radio program title, a user-defined radio station identifier, a television station call letter, a television station call number, a television channel number, a television program title, a user-defined television station identifier, a video program title, or a combination thereof.

In one embodiment, the media control logic module 304 can transmit the data 338 related to the audio content to the voice synthesis logic module 342. The voice synthesis logic module 342 can process the data 338 and generate verbal audio outputs or other sound cues that inform the user of the audio content that is output via the speakers 332. For example, the voice synthesis logic module 342 can speak the name of a song before the song is output. In another example, the voice synthesis logic module 342 can periodically speak the station or call sign of a television or radio station that is being output. The voice synthesis logic module 342 can be used together with, or in place of, the set-top box display 314. Further, the use of the voice synthesis logic module 342 can be selectable by a user, via voice command, remote control, or set-top box keys.

In a particular embodiment, the audio content may be derived from multimedia content, such as broadcast television content, recorded television content, or video content, such as VOD content, the media control logic module 304 can filter, or command a suitable device to filter, video content out of the multimedia content, such that no video or graphic content is transmitted to the set-top box display interface 312.

In an exemplary embodiment, the media control logic module 304 can receive a voice command 334 requesting a list of available audio content or an available group of audio content, such as the tracks on an album, the albums in a music genre, VOD movies in a new release category, television program airing at a specified time, and the like. The media control logic module 304 can retrieve data 338 related to audio content identified by the voice command(s) 334 received at the audio input device 326. In one embodiment, the media control logic module 304 can submit one or more queries to the memory device 306 and retrieve data 338 that matches or at least substantially matches the voice command(s) 334 from the audio content and information files 320. In another embodiment, the media control logic module 304 can submit one or more requests for the data 338 to an IPTV system, via the private IPTV access network 322. In this embodiment, the media control logic module 304 generates one or more requests and transmits the one or more requests to the private IPTV access network 322, via the network interface 308.

Additionally, the media control logic module 304 can include instructions to transmit the data 338 to the display 314. The data 338 can be displayed as scrolling text across the display 314, for example, or constituents of a list can be displayed one at a time at the display 314. In another embodiment, the media control logic module 304 can include instructions to transmit the data 338 to the voice synthesis logic module 342. The voice synthesis logic module 342 can process the data 338 and generate verbal audio outputs that inform the user of available audio content that corresponds to the user's request in the voice command(s) 334. For example, the voice synthesis logic module 342 can speak the name of each song in a musical category. In another example, the voice synthesis logic module 342 can speak the names of each television program airing at a specified time.

In an illustrative, non-limiting embodiment, the media control logic module 304 can receive a voice command 334 requesting a multi-level menu or portion thereof. The media control logic module 304 can retrieve one or more menus identified by the voice command(s) 334 received at the audio input device 326. Additionally, the media control logic module 304 can include instructions to transmit the menus, or data corresponding to the menus, to the voice synthesis logic module 342. The voice synthesis logic module 342 can process the menu data and generate verbal audio outputs that inform the user of available menu selections and allow the user to navigate through multiple menu levels. For example, if a voice command 334 is ‘main menu,’ the set-top box device 302 can output ‘say 1 for audio settings; say 2 for music categories; say 3 for radio stations; say 4 for video-on-demand; say 5 for user options,’ or other suitable items. In another example, the user can say ‘music categories,’ and the set-top box device can output ‘say 1 for country; say 2 for popular music; say 3 for classical,’ and similar verbal statements. In one embodiment, if the user designates classical music by speaking ‘three,’ a next menu level can be output by the set-top box device, such as, ‘say 1 for Mozart; say 2 for Chopin; say 3 for Vivaldi,’ and similar verbal statements.

The set-top box device 302 may receive inputs from a remote control 344 via a remote control interface 346, or from similar keys disposed on a side of the set-top box device 302. The inputs can be received in addition to, or in place of, voice command(s) and can designate audio content or groups of audio content that the user wishes to hear. Further, the inputs can designate lists of audio content that the user wishes to browse. Additionally, the inputs can request and make selections from multi-level menus, or portions thereof. In an illustrative embodiment, the inputs can indicate whether the user wishes to have data related to audio content displayed via the set-top box display 314 or output verbally via the speakers 332.

Referring to FIG. 4, a particular illustrative embodiment of a method of providing audio content is disclosed. At block 400, a voice command is received at a set-top box device. In a particular embodiment, the set-top box device can output a signal at block 402, such as a sound cue or verbal phrase, indicating that the system has received and recognized the voice command. The voice command can be received via an audio input device, such as a microphone or other transceiver. In a particular embodiment, the voice command identifies audio content that a speaker wishes to hear. For example, the voice command can identify a song title, a song collection title, an artist name, a song track number, a user-defined audio file identifier, a radio station frequency, a radio station call letter, a radio station call number, a radio program title, a user-defined radio station identifier, a television station call letter, a television station call number, a television channel number, a television program title, a user-defined television station identifier, a video program title, or a combination thereof.

At block 404, the set-top box determines particular audio content that is identified by the voice command(s). This determination can be made by a media control logic module, or a separate processor or computer program, within the set-top box device.

Moving to decision step 406, the set-top box determines whether the audio content identified by the voice command(s) is available. For example, a media control logic module, or a separate processor or computer program, within the set-top box device can compare the audio content identified by the voice command with a directory or list of available audio content that is stored in the set-top box memory, at a server accessible to the set-top box device, or a combination thereof. Alternatively, the set-top box device can determine whether the audio content is stored at the set-top box device and submit a query to the server requesting an indication of availability.

If it is determined that the audio content is not available, the method proceeds to block 408, and an error message indicating that the audio content is unavailable is displayed on a set-top box display portion disposed on a visible side of the set-top box device. The method then moves to block 418 and continues as described.

Returning to decision step 406, if the audio content identified by the voice command(s) is available, then the method continues to block 410, and the audio content is retrieved. The audio content can be retrieved from audio files stored within the set-top box memory. In a particular embodiment, the set-top box device can submit a request to the server for the audio content. Moving to block 412, data related to the audio content is retrieved. The data can be retrieved with the audio content, or separately from the audio content.

Continuing to block 414, the set-top box device outputs the audio content. In a particular embodiment, a media control logic module, or separate processor within the set-top box device, can transmit an audio signal corresponding to the audio content to one or more audio output devices, such as speakers, that are integrated with, or coupled to, the set-top box device. At block 416, the set-top box device displays the data related to the audio content. The set-top box device can transmit the data to a display that is disposed on a visible side of the set-top box device. The set-top box display is separate from a television display that may be coupled to the set-top box device.

Moving to decision step 418, the set-top box determines whether a new voice command has been received. If a new voice command is received, the method returns to block 404. Conversely, if no new voice command is received, the method terminates at 420.

Referring to FIG. 5, a second embodiment of a method of providing audio content is illustrated. At block 500, an audio input is received at a set-top box device. The audio input can be received via an audio input device, such as a microphone or other transceiver. At block 502, the set-top box determines whether the audio input includes one or more voice commands that can be processed and executed by the set-top box device. This determination can be made by a computer program embedded in a memory of the set-top box device, by a media control logic module within the set-top box device, by a voice command logic module within the set-top box device, or a combination thereof. If the audio input does not include a voice command, the method terminates at 504. On the other hand, if the audio input includes a voice command, the method proceeds to decision step 506.

At decision step 506, the set-top box device can determine whether the voice command is received from a new user. For example, a ‘new user’ voice command can be received at the set-top box device, or the set-top box device can determine that the voice command does not match a voice print that is stored by a memory within the set-top box device. If the voice command is not received from a new user, the method continues to decision step 512 and continues as described. Conversely, if the voice command is received from a new user, the method proceeds to block 508. At block 510, the set-top box can prompt the user for one or more voice prints that will be used to identify the user as the source of various voice commands. For instance, the set-top box device can prompt the user for a single voice print, from which the voice character of other commands spoken by the user can be extrapolated. Alternatively, the set-top box device can prompt the user for voice prints for each of a plurality of commands, such as ‘play,’ ‘stop,’ ‘pause,’ and the like. In another example, the set-top box device can prompt the user for voice prints for each of a plurality of menu selection identifiers, such as ‘one,’ ‘two,’ ‘three,’ and so on. In a particular embodiment, the set-top box device can prompt the user for designations of any audio content that the user wishes to restrict, such as audio portions of television or other programs that are unsuitable for children. Moving to block 510, the voice prints and any content restrictions are received and stored at the set-top box device. The method then proceeds to decision step 512.

At decision step 512, the set-top box determines whether the voice command received identifies audio content. If the voice command does not identify audio content, such as a stop command, a pause command, a next track command, a previous track command, a next video program command, a previous video program command, or a combination thereof, then the method proceeds to block 514, and the action identified by the voice command is executed. The method may then terminate at 504.

Returning to decision step 512, if the voice command identifies audio content, the method continues to block 516. A voice command that identifies audio content can include, for example, a song title, a song collection title, an artist name, a song track number, a user-defined audio file identifier, a radio station frequency, a radio station call letter, a radio station call number, a radio program title, a user-defined radio station identifier, a television station call letter, a television station call number, a television channel number, a television program title, a user-defined television station identifier, a video program title, or a combination thereof. In a particular embodiment, an action command, such as a play command or a retrieve command, can be combined with an identification of audio content.

Moving to block 516, the set-top box determines the audio content identified by the voice command. The method continues to decision step 518, and the set-top box determines whether the audio content identified by the voice command is restricted. In a particular embodiment, the set-top box device can compare the identified audio content with a list or directory of restricted audio content that has been designated by a user at block 508 and 510. If the audio content identified by the voice command is not restricted, the method continues to decision step 520 and continues as described. On the other hand, if the audio content identified by the voice command is restricted, the method moves to block 522, and the voice command is compared to one or more voice prints of authorized users that are stored in the set-top box memory. At decision step 524, the set-top box device determines whether the voice command matches the voice print(s) of an authorized user. If a match is found, the method continues to decision step 520; whereas, if a match is not found, the method proceeds to block 526, where the audio content is blocked from output, and an error message indicating that the requested audio content is unavailable is transmitted to a display disposed on a visible side of the set-top box device.

Moving to decision step 520, the set-top box device determines whether the audio content identified by the voice command(s) is stored at the set-top box device. For example, a media control logic module or separate computer program within the set-top box device can compare the audio content identified by the voice command with a directory or list of available audio content that is stored in the set-top box memory. If the audio content identified by the voice command is stored in the set-top box memory, the method proceeds to block 528 and continues as described. On the other hand, if the audio content identified by the voice command is not stored at the set-top box device, the method moves to block 530.

In a particular embodiment, the set-top box can issue a request for the audio content identified by the voice command, and data relating to the audio content, to an IPTV system via an access network, at block 530. For example, a media control logic module, or a separate computer program or processor, within the set-top box device can issue the request via a network interface within the set-top box device that is coupled to communicate with an IPTV access network. The method continues to decision step 532, and the set-top box device determines whether it has received the requested audio content and related data. In one embodiment, the set-top box device may receive a response via the access network indicating that the requested audio content is unavailable at the IPTV system. The method then proceeds to block 538, and an error message indicating that the requested audio content is unavailable is transmitted to a display disposed on a visible side of the set-top box device. The method then moves to decision step 546 and continues as described.

Returning to decision step 532, if the set-top box determines that it has received the requested audio content and related data via the access network, the method proceeds to decision step 534. At decision step 534, the set-top box determines whether the audio content is derived from multimedia content, such that the set-top box has received video content with the audio content. For instance, where the voice command indicates that the user desires to listen to the audio portion of a television broadcast program, the set-top box device can receive the multimedia content of the television broadcast program in response to the request issued at block 530. When the set-top box receives only audio content, the method moves to block 542, and continues as described. When the set-top box receives multimedia content, the method moves to block 536, and the set-top box device filters out the video content to retrieve the audio content via the media control logic module, or a separate processor, filter, or computer program, within the set-top box device. The method then proceeds to block 542.

Returning to decision step 520, if the audio content identified by the voice command(s) is stored at the set-top box device, the method continues to block 528, and the audio content is retrieved from the set-top box memory. Moving to block 540, data related to the audio content is also retrieved from the set-top box memory. The data can be retrieved with the audio content, or separately from the audio content.

Continuing to block 542, the set-top box device outputs the audio content retrieved from the set-top box memory, at block 538, or received via the IPTV access network, at decision step 532. In a particular embodiment, a processor or media control logic module can transmit an audio signal corresponding to the audio content to one or more audio output devices, such as speakers, that are integrated with, or coupled to, the set-top box device. At block 544, the set-top box device displays, outputs, or displays and outputs, the data related to the audio content. The set-top box device can transmit the data to the display that is disposed on a visible side, such as a front panel, of the set-top box device. In one embodiment, the set-top box device can output the data related to the audio content, for example, as verbal audio outputs.

Moving to decision step 546, the set-top box determines whether a new voice command has been received. If a new voice command is received, the method returns to block 512. Conversely, if no new voice command is received, the method terminates at 518.

Referring to FIG. 6, an embodiment of a set-top box device is illustrated and designated generally at 600. The set-top box device 600 includes a housing 602 having at least one visible side, such as the visible side 604. In a particular embodiment, a display 606 is disposed on the visible side 604. Additionally, one or more speakers 608 can be integrated with or coupled to the housing 602. In one embodiment, the set-top box device 600 can include a keypad 624, which a user may use to input selections and other commands to the set-top box device 600.

In an illustrative embodiment, the display 606 can contain a plurality of fields 610, 612, 614. Each field can display a portion of data related to audio content that is output via the speakers 608. For example, if live radio content is broadcast via the speakers 608, the display can include a frequency of a radio station at the field 610; a radio program title at the filed 612; and a time of day, or an amount of time that the audio content has been output, at the field 614.

As illustrated, the set-top box device 600 can be coupled to an external display device, such as a television monitor 616. In an illustrative, non-limiting embodiment, the set-top box device 602 can be adapted to transmit a user interface 618 to the television monitor 616. The user interface 618 can include a plurality of regions, such as a video content display region 620 and an informational content selection region 622.

Many users may prefer to listen to audio content when conducting other activities. For instance, a user may wish to listen to a television news program, while reading or supervising children. Alternatively, a user may prefer to output only the audio content associated with a music video channel at a party, or where the video content may be unsuitable for children who are near the television monitor. In another example, users may wish to save power consumption associated with television monitors, by not displaying a screen associated with a music content channel. Nonetheless, users may desire to access many forms of audio content, including audio portions of broadcast television programs, Internet radio, satellite radio, recorded music, or recorded television or video programs, without proximity to, or manipulation of, separate electronic components.

Thus, in accordance with the various embodiments, the systems and methods described herein provide both stored and broadcast audio content that may be retrieved in response to voice commands received at a set-top box device. The audio content can be stored at the set-top box device or received from an IPTV system, or both. Additionally, video or graphic content, including content associated with multimedia content, may be blocked from display at a display device external to the set-top box device while the audio content is output. Data related to the audio content is displayed at a set-top box display disposed on a visible side of the set-top box device, so the user can the audio content being output by the set-top box device.
